Importance of selectively permeable membrane
Witryna30 sie 2024 · All cells are enclosed with a cell membrane. A selectively permeable cell membrane is one that allows certain molecules or ions to pass through it by means of active or passive transport. Witryna24 wrz 2024 · Selective permeability is an essential feature of the plasma membrane. Without it, the cell would be unable to control the molecules entering and leaving the cell. This would disrupt the cell’s normal functioning, leading to a malfunctioning cell and eventually cell death.
